Find the value of x to the nearest tenth

Mathematics
1 answer:
Dafna11 [192]3 years ago
8 0

Answer:

x = 3√5

Step-by-step explanation:

we can use the Pythagorean Theorem twice, first to find the longer leg of the left triangle:

7² + b² = 10²

b² = 100-49

b² = 51

b = √51 which we can simplify to be √9·√3·√3 = 3·3 = 9

we can use the Pythagorean Theorem next to find 'x':

x² + 6² = 9²

x² + 36 = 81

x² = 45

x = √45 = √9·√5 or 3√5

Y=3x -2 what is the slope and y intercept
Olin [163]

The slope is y=3x-2, or if you had to rewrite it, 3x-2 is the slope. The y intercept could be found using the previous formula, y=3x-2. If x were to be equal to 5 for example, you would have to multiply that by 3, then subtract it by 2, and you get your y intercept, which would equal 13 (THIS IS AN EXAMPLE).

Reflect triangle stu across line st which of these is a valid reason why the image u will coincide with j
hjlf

Answer:

4. None of the above

Step-by-step explanation:

Reflection is a type of transformation that can be used to change the orientation of a given figure or shape without changing it size and shape.

When triangle STU is reflected across ST, the image U coincides with J because the two are on the opposite side and at the same distance from ST. Therefore, J is like the image of U.

How would you write the equation with a slope of 2/3 and a y-intercept of (0,-3)?
rosijanka [135]

Answer:

y = (2/3)x - 3

Step-by-step explanation:

Slope-intercept form: y = mx + b

Note that:

y = (x , y)

m = slope

x = (x , y)

b = y-intercept.

The point is given to you. Note that:

(x , y) = (0 , -3) ∴

x = 0

y = -3

The slope = m = 2/3

Plug in the corresponding numbers to the corresponding variable:

y = mx + b

-3 = (2/3)(0) + b

-3 = 0 + b

b = -3

Plug in -3 for b in the equation:

y = mx + b

y = (2/3)x -3

y = (2/3)x - 3 is your equation.
